unplug_io_fn was zero filled...RIP was 0, so I knew I was following a bad function pointer, but the rest of the trace was just handle_mm_fault and a few others leading to block_sync_page.
Swap never showed in there, and I was a overly fixated on tracking down someone calling lock_page without the inode pinned. The good news is that I'm now pretty sure we don't call lock_page without the inode pinned ;-)
